En cirugía, la investigación actual ha demostrado una mejoría en el rendimiento para la realización de nudos abiertos, habilidades laparoscópicas y robóticas, mientras también contrarresta las exigencias subjetivas materiales. Sin embargo, surgen aspectos éticos ante la posible aplicación de la tDCS en cirugía, como son la seguridad, la coerción, la justicia distributiva y la equidad, situaciones que deben considerarse antes de su implementación. CONCLUSIÓN La estimulación neurológica puede mejorar las habilidades motoras y cognitivas de los profesionales sanitarios con repercusión en la seguridad del paciente. Su implementación requerirá de protocolos y regulaciones específicas para equilibrar los beneficios con los dilemas éticos asociados y garantizar su seguridad para médicos y pacientes.Previous studies have found that the primary pathogenesis of liver cancer progression is linked to excessive cancer cell proliferation and rapid metastasis. Although therapeutic advances have been made for the treatment of liver cancer, the mechanism underlying the liver cancer progression has not been fully addressed. In the present study, we explored the role of spliced X-box binding protein 1 (XBP1) in regulating the viability and death of liver cancer cells in vitro. Our study demonstrated that XBP1 was upregulated in liver cancer cells when compared to the primary hepatocytes. Interestingly, the deletion of XBP1 could reduce the viability of liver cancer cells in vitro via inducing apoptotic response. Further, we found that XBP1 downregulation was also linked to proliferation arrest and migration inhibition. At the molecular levels, XBP1 inhibition is followed by activation of the Mst1 pathway which promoted the phosphorylation of c-Jun N-terminal kinase (JNK). Then, the active Mst1-JNK pathway mediated mitochondrial reactive oxygen species (mROS) overproduction and then excessive ROS induced cancer cell death. Therefore, our study demonstrated a novel role played by XBP1 in modulating the viability of liver cancer cells via the Mst1-JNK-mROS pathways. © 2020 Wiley Periodicals, Inc.Immune checkpoint inhibitors have revolutionized cancer therapy leading to exceptional success. However, there is still the need to improve their efficacy in non-responder patients. Natural Killer (NK) cells represent the first line of defence against tumours, due to their ability to release immunomodulatory cytokines and kill target cells that have undergone malignant transformation. Harnessing NK cell response will open new possibilities to improve tumour growth control, and indeed inhibitory checkpoints expressed on these innate lymphocytes represent a promising target for the next-generation immunotherapy. In this review, we will summarize recent evidences on the expression of NK cells receptors in the cancer setting, with a focus on the inhibitory checkpoint Programmed cell death protein 1 (PD-1). We will also highlight the strength and limitations of the blockade of PD-1 inhibitory pathway, and suggest new combination strategies that may help to unleash more efficiently NK cell antitumour response.

Using data from a representative German sample including 7702 secondary school students of immigrant background from 1643 classrooms, we examined how the attended school track and four aspects of ethnic classroom composition relate to adolescents' cultural identity (i.e., their ethnic identity and mainstream identity). Two-level structural equation models indicated that students' ethnic identity was not systematically associated with the attended school track and the ethnic composition of the classroom. However, attending the academic school track, a classroom with a low proportion of classmates with immigrant background and frequently using German with classmates related positively to mainstream identity. Ethnic diversity and proportion of co-ethnics in class did not relate to mainstream identification. Our findings suggest that the ethnic identity of adolescents with an immigrant background in Germany is largely independent from the different socialisation contexts related to school tracks and the ethnic classroom composition. Yet, students' with a strong mainstream identity cluster in certain school contexts. © 2020 The Authors.

Cinnamic acid as an unsaturated carboxylic acid might prevent inflammation and periodontal destruction. The present study aimed to evaluate the effects of cinnamic acid in two different forms as free cinnamic acid and cinnamic acid liposome on experimental periodontitis in Wistar rats. METHODS Thirty-two female rats were used in the present study. Four main groups were created as follows C control group; P periodontitis group; C-P free cinnamic acid-administered periodontitis group; and CL-P cinnamic acid liposome applied group. Periodontitis was induced via ligating 4-0 silk sutures around lower first molar teeth on both right and left mandibles. The study duration was 30 days, and the ligatures were removed from half of the rats in the periodontitis-induced groups. The other half carried the ligatures throughout 30 days, and all rats were euthanized at 30th day. Mane periodontitis group, and cinnamic acid decreased these levels but not to a significant level except for the cinnamic acid liposome ligature removal group, which had significantly lower values in the PPAR-γ and COX-2. OPG levels were lower in the periodontitis group compared to the other groups. Cinnamic acid significantly decreased RANKL and increased OPG levels. CONCLUSION Periodontitis caused increased inflammation and bone destruction accompanied by increased PPAR-γ, COX-2, and RANKL levels and osteoclast counts. Cinnamic acid decreased osteoclast counts and inflammation and increased osteoblast counts and OPG expression in the present animal model of periodontitis. © 2020 John Wiley & Sons A/S.

The sequence divergence of the bovine, mouse, and human Slo3 α-subunit revealed a rapid evolution rate across different species. The rat Slo3 (rSlo3) channel has not been cloned and characterized previously. EXPERIMENTAL APPROACH We used molecular cloning, electrophysiology (inside-out patches and outside-out patches), and mutagenesis to investigate the biophysical properties and pharmacological characteristics of the rSlo3 channel. KEY RESULTS The rat Slo3 channel (rSlo3) is gated by voltage and cytosolic pH rather than intracellular calcium. The characteristics of voltage-dependence, pH-sensitivity, and activation kinetics of the rSlo3 channel differ from the characteristics of other Slo3 orthologues. In terms of pharmacology, the 4-AP blockade of the rSlo3 channel also shows properties distinct from its blockade of the mSlo3 channel. Iberiotoxin and progesterone weakly inhibit the rSlo3 channel. Finally, we found that propofol, one of the widely used general anaesthetics, blocks the rSlo3 channel from both intracellular and extracellular sides, whereas ketamine only blocks the rSlo3 channel at the extracellular side. CONCLUSIONS AND IMPLICATIONS Our findings suggest that the rSlo3 channel possesses unique biophysical and pharmacological properties. Our results provide new insights into the diversities of the Slo3 family of channels, which are valuable for estimating the effects of the use of these drugs to improve sperm quality.

Alongside a broad panel of bio-informatics tools and databases, NGS technologies have unprecedentedly improved the molecular diagnosis rate and the identification of new genes associated with rare disorders. However, about 50% of patients remain without a final diagnosis. Here, we highlight the utility of NGS applications in developmental anomalies and intellectual disability, illustrating their main advantages and pitfalls. Through specific examples, we suggest novel strategies and tools for identifying the molecular bases in the remaining patients, and we outline future challenges.

Although found at very low concentrations in vivo, these metabolites play key roles in health and disease, particularly in development and regulating immune cell responses, by binding to effector proteins such as LXRα, RORγ and Insig and directly or indirectly regulating transcriptional programs that affect cell metabolism and function. In this review we summarise the routes by which oxysterols can be generated and subsequently modified to other oxysterol metabolites, and highlight their diverse and profound biological functions and opportunities to alter their levels using pharmacological approaches.

FHOD3 has emerged as a novel disease-causing gene for this phenotype, but the relevance and clinical implication of copy-number variations (CNVs) have not been determined. In this study, CNVs were evaluated using a comparative depth-of-coverage strategy by next-generation sequencing (NGS) in 5493 HCM probands and 2973 disease-controls. We detected three symmetrical deletions in FHOD3 that involved exons 15 and 16 in three HCM families (no CNVs were detected in the control group). These exons are part of the diaphanous inhibitory domain of FHOD3 protein, considered a cluster of mutations for HCM. The clinical characteristics of the affected carriers were consistent with those reported in FHOD3 in previous studies. This study highlights the importance of performing CNV analysis systematically in NGS genetic testing panels for HCM, and reinforces the relevance of the FHOD3 gene in the disease. © 2020 John Wiley & Sons A/S.

El objetivo de este estudio fue describir los esquemas de formación de los aspirantes en laparotomía de urgencia y su asociación con los resultados postoperatorios. MÉTODOS Todos los pacientes a los que se realizó una laparotomía de urgencia entre diciembre del 2013 y noviembre del 2017 se obtuvieron a partir de la base de datos de la Auditoría Nacional de Laparotomía de Urgencia (National Emergency Laparotomy Audit, NELA). Los pacientes se agruparon según la experiencia del cirujano; cirujanos en periodo de formación (residentes, speciality registrar) o consultores (incluyendo los que habían completado la especialidad). Se investigaron las tendencias entre los residentes por universidad, tamaño del hospital y hora del día de la cirugía. Se realizaron análisis de regresión univariable y ajustados para la mortalidad a los 90 días y la reoperación, así como análisis de subgrupos para los procedimientos quirúrgicos de colectomía segmentaria, intervención de Hartmann, liberación de bridas y la sutura de una úlcera péptica perforada.
